CVE-2026-78691 ash-project CVE debrief

Who should care

Users and administrators of ash_sql, particularly those using versions from 0.1.1-rc.10 before 0.7.1, should review and apply patches to prevent potential SQL injection attacks. Additionally, developers and security teams should be aware of the vulnerability and implement compensating controls to mitigate potential risks. This includes conducting a thorough inventory of systems and applications using ash_sql to identify potential exposure and implementing input validation and sanitization to mitigate the vulnerability. Security teams should also monitor relevant systems for potential attacks and implement incident response plans in case of a breach. Asset owners and operators should prioritize patching and vulnerability management for ash_sql deployments. Vulnerability management teams should track exceptions and retest remediated assets to ensure the vulnerability is fully mitigated. Security teams should also review compensating controls for exposed systems while remediation is scheduled and verified. IT operations teams should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Monitoring and detection teams should check relevant monitoring, detection, and logs for exposed assets that need extra review. Project managers should track the remediation progress and ensure that all affected systems are patched or mitigated. Compliance teams should verify that the necessary controls are in place to meet regulatory requirements. Communication teams should inform stakeholders about the vulnerability and the necessary actions to take. Help desk and support teams should be aware of the vulnerability and provide guidance to users on how to mitigate it. Auditors should review the remediation efforts and ensure that they meet the necessary standards. Penetration testers and red teamers should test the vulnerability and provide feedback on the remediation efforts. Blue teamers and incident responders should be aware of the vulnerability and be prepared to respond to potential attacks. Threat hunters should monitor for potential attacks and provide feedback on the remediation efforts. Security architects should review the

Technical summary

The CVE-2026-78691 vulnerability in ash_sql allows users to inject live SQL LIKE wildcards by improperly neutralizing special elements in data query logic. This can lead to unauthorized data access or query manipulation. The issue affects ash_sql versions from 0.1.1-rc.10 before 0.7.1. The vulnerability has a CVSS score of 2.1 and is classified as LOW severity. The escape helpers in AshSql.Expr prefix % and _ with a backslash but never escape a backslash already present in the input, which defeats the escaping mechanism. This allows an attacker to manipulate the SQL query, potentially leading to data breaches or system compromise. Users and administrators should review and apply patches for ash_sql to prevent potential SQL injection attacks.

Defensive priority

Review and apply vendor patches for ash_sql to prevent potential SQL injection attacks.

Recommended defensive actions

• Review and apply vendor patches for ash_sql to prevent potential SQL injection attacks.
• Conduct a thorough inventory of systems and applications using ash_sql to identify potential exposure.
• Implement compensating controls, such as input validation and sanitization, to mitigate the vulnerability.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
